Exchange of information through the channels of communication can be
unsafe. Communication media are not safe to send sensitive information so it is
necessary to provide the protection of information from disclosure to unauthorized
persons. This research presented the method to information security is done
through information hiding into the cover image using a least significant bit (LSB)
technique, where a text file is encrypted using a secret sharing scheme. Then,
generating positions to hiding information in a random manner of cover image,
which is difficult to predict hiding in the image-by-image analysis or statistical
analyzes. Where it provides two levels of information security through encryption
of a text file using the secret sharing and the generating random positions of hiding.
This method has been in hiding a text file and recovered without loss of
information, as well as not noticing any deformation of the image. Where it was
hiding a text file size of 20 KB in image cover (250x250) pixels, the result of MSE
is 0.696 and PSNR is 49.211.

Four different ratios of composites were prepared by varying the
wool glass, at different additive weight percentages (0, 0.2, 0.4, 0.6 wt. %)
in order to study the effect of glass wool reinforcement on mechanical and
chemical properties of GW-reinforced polyester composites. The vacuum
bagging technique was adopted for the fabrication of hybrid composite
materials. Afterword many mechanical properties as hardness, impact
resistance, and compression resistance for these hybrid composites were
evaluated according ASTM Standards. The mechanical properties were
improved as the fibers reinforcement content increased in the matrix
material. The chemical properties were improved as increased the weight of
glass wool. The chemical and mechanical properties have been increased
for maximum value when glass wool fiber has reached 0.6% wt.

Current work is aimed to preparation the nanocomposites laminates
of low density and good durability to use in structural applications. So, in this
paper, the preparation and compare of some mechanical properties of two
groups of tri-polymer blends composites consisting of ((93% unsaturated
polyester resin (UP)+(5%PMMA) (Poly methyl methacrylate)+2%NR
(Natural Rubber)) as the matrix materials. Added the reinforce materials
(silica (SiO2) and zirconia (ZrO2) nanoparticles) individually, with different
volume fraction of (0, 0.5, 1, 1.5%) to the ternary polymer blends according
to the following formula:- [((100-X) (93%UP)+2%NR+5%PMMA): (X%SiO2
or X% ZrO2)] The first group is composed of matrix material reinforced with
zirconia (ZrO2) nanoparticles with average diameter of nanoparticles
(56.88nm) and the second group is composed of matrix material reinforced
with silica (SiO2) nanoparticles with average diameter of nanoparticles
(24.59nm). Then used as a matrix material for the preparation of hybrid
laminar composites materials, reinforcement with one and two layers of
woven carbon fibers The research included the study of the influence of
volume fraction of nanoparticles on some of mechanical and physical
properties like flexural strength, flexural modulus impact strength, and impact
fracture toughness, in addition to test infrared spectroscopy (FTIR) and all of
these tests were carried out at laboratory temperature. Search results have
shown that the values of (flexural modulus and impact strength and fracture
toughness) increases with the increase of the nanoparticles ratios in polymer
blend nano composite of prepared samples. While flexural strength value
decreases with the increase in the volume fraction of nanoparticles in polymer
blend nano composite. The fracture energy of the of hybrid laminar
composites is higher than those containing only the nanoparticles powders.
Morphology test by scanning electron microscope indicates that a good
adhesion or interfacial interactions between the Nano powders particles,
carbon fibers and components of ternary polymer blend. Which results in
higher the carbon fibers efficiency factor, and hence higher mechanical
strength. So, the hybrid laminar nano composites, which appear high flexural
modulus and impact strength and fracture toughness, can be foreseen to
provide valuable contribution to high performance structural applications.

Engineering and Technology Journal, 2018, Volume 36, Issue 1B, Pages 25-32
DOI: 10.30684/etj.36.1B.4

In this research, a watermark algorithm is proposed to embed a secret
message in a digital video. The proposed algorithm exploits edges and corners
regions in images, to be hosts for hiding secret bits. Embedding in these regions
is consider optimal since these regions featuring with colors variation, so
embedding will not effect on uniform distribution of colors, and on transparency
requirement. The process of embedding and extracting watermarked massage is
implemented by decomposition digital video to several images (frames), then
selecting the edges and corners regions to be host locations, Least Significant
Bit (LSB) techniques are used to embed watermarked message in images of
digital video. Investigations results proved that number of hidden bits in corner
region is small in comparison with edges regions, but it is harder to detect. Text
message before embedded in video frames is encrypted by Advanced Encryption
Algorithm (AES) to increase security and robustness of watermarking process.
